This nesten relotioi p oi the r 1 is clearly indicated :5; m e l oi the drowine, wherein the clamping levei' hoe been swung in the direction oi the arrow it from to position shown in Figure '2 through the intermediate position of Figure 3 one into nested relationship with the clamping ring I. In this position the saddle ll bridges the gap between the slightly spaced ends of the clamping ring, and partially houses the clamping lever, the projecting end of the clamping lever, which is also of, generally U-shaped cross section embracing one end portion of the. clampins ring and constituting a continuation of the saddle l0.

Formed on the clamping lever is a deiormable lug Ii adapted to be bent inwardly so as to underlie the clamping ring and prevent accidental release thereof. If desired, the saddle and lever may each be provided with cooperating openings l1 and I8 respectively, so positioned as to come into registration with. the parts in the position of Figure 1 to receive a sealing wire ll secured by a seal 2|.

In Figure i there is shown a dotted line ll extending betweenthe pivotal mountings for the saddle and clamping lever respectively, the pivot 22 being shown as located at one side of this dotted line. By reason of this relationship of the parts, as the levers are moved to contract the clamping ring, th'e'pivot I! will first move into and then across the line of the other pivots, thus exerting a holding action in the nature of a toggle which prevents accidental displacement of the parts.

Acomparisonotl lgures2and3willshow that the arrangement of the clamping lever and saddle is such that the end portions of the clamping ring may be drawn toward each other in a straight line movement, the saddle and clamping lever both moving in a clockwise direction about their respective pivotal mountings during the contracting operation, the clamping lever constituting a lever 01 the second class in which the load is applied at a point intermediate its i'ulcrum on the clamping ring and the tree outer end thereof. This enables the saddle and clamping lever to be so mounted asto alvlaysoocupya position entirely on one side. of the general plane of the clamping ring, and enables themtine structure to be utilised in the position showninr'igureLorbodilyinver-tedsothatthe saddle and clamping lever both underlie the clamping ring, although it is normally contemplatedthatthepartswillbeutiliaedinthemannernrstdescribed.

disclosed may be made without departing either from the spirit of my invention or the scope of my broader claims.

I claim:

1. A head retaining device for containers, comprising a clamping ring having end portions adapted to move toward and from each other, a saddle pivotally connected to one of said end portions, a lever pivotally connected to the other of said end portions, a pivotal connection between said saddle and lever at a point between the free end of said lever and its pivotal mounting on the clamping ring, said lever being movable generally in a plane transverse to the plane of said ring, said pivotal connection being adapted upon movement of the parts'to clamping posi tion to cross the'line oi the pivots connecting the saddle and lever, respectively, to said end portions, and means to positively maintain .the end portion of the lever in place when the parts are in clamping position.

2. A head retaining device for containers, com- 'prilng a clamping ring having end portions adapted to move toward and from each other, a-saddle pivotally connected to one oi said end portions, a lever pivotaily connected to the other or said end portions, and a pivotal connection between said saddle and lever at a point between the tree end of said lever and its pivotal connection with the clamping ring, said lever being movable generally in a plane transverse to the plane oi said ring, said pivotal connection being adapted upon movement the parts to clamping position to cross the line 0! the pivots connecting the saddle and lever, respectively, to said end portions, at least one of said saddle, lever S.
